Claims

[Scope of utility model registration request]

A rotary shaft whose front end is connected to the front wheel steering link mechanism and extends rearward and rotates according to the steering condition of the front wheels, and a rotary shaft which constitutes the rear wheel steering link mechanism or is connected to the same mechanism and whose front end extends rearward and rotates in the left-right direction. an actuating rod that steers the rear wheels by means of an actuator, and a connecting mechanism that connects the actuating rod with the rotating shaft, and the connecting mechanism is fixed to the rear end of the rotating shaft so that the actuating rod steers the rear wheels in the left-right direction by rotation of the rotating shaft. a first swinging arm that swings; and a first swinging arm that is supported by the swinging arm so as to be swingable in the left-right direction, extends along the swinging arm, and whose swinging end portion is swingable with respect to the actuating arm. a second swing arm that is connected; an actuator that swings the swing arm to control the amount of swing relative to the first swing arm; and a second swing arm that is connected to both swing arms and swings the first swing arm. A rotating force arm that moves left and right in response to the movement of the second swing arm and rotates in the vertical direction in response to the swing of the second swing arm is fitted with a rotation force member that extends in the left and right direction of the first swing arm. When the first swinging arm is not swinging, it engages with the rotating arm to restrict the rotation of the rotating arm, and the swinging of the first swinging arm causes the rotating arm to move laterally and engage with the rotating arm. A rear wheel steering device for a front and rear wheel steered vehicle, comprising a guide provided with a cam groove that releases the coupling and allows rotation of the rotary arm.
